Again, very simple to use, laid like a regular amp. There's also the DI recording out which is useful (but doesn't sound THAT great) and a built in attenuator which is quite useful too. I think these are available on nearly every one of koch's amps.


The sound is different because of the El34s of course. The cleans are cleaner and the distortion is warmer and rounded than the studiotone. Of course there's less break up too when you crank the clean cause of the El34s. But aside from that I can't really say that the tones are TOO different, they definitely have the same vibe and the same, let's say, DNA. If you get a chance to play both of them side by side of course you will notice the differences but you will definitely feel the same vibe from both amps. It just depends on your needs in terms of features and how much clean headroom you want that would depend on which amp to go for.


Another amazing amp from Koch. Though it has the same soul, it's definitely improved upon with more headroom and separate EQ channels for both clean and dirty channels. All the same as the studiotone with the great tones, the power soak, and the recording out with cab emulation.

A very very very worthy amp!!!
